Profile: Validyne Engineering Corp. designs, markets, manufactures, and services a broad range of pressure transducers & transmitters having full scale ranges from 0.1 in h20 to 12,500 psi, and signal conditioning & data acquisition systems. Our laboratory pressure transducers allow re-ranging by the user to meet any test and measurement application on short notice, and feature fast response for transient analysis. Our model P55 is a compact differential pressure transmitter designed for industrial pressure measurement applications. The variable reluctance sensing technology allows the P55 to be used in a wide variety of low pressure measurements where fast dynamic response, high resistance to vibration, and signal stability through temperature change is required. The P55 will accept both liquids & gases directly at the sensing diaphragm. There are no internal isolation fluids to slow the sensor response, or cause temperature drift errors. The P300 D/A pressure transducer is designed for direct application in DC strain gauge instrumentation systems which require low pressure ranges not generally available in strain gauge transducers. Functionally, it is a direct replacement for a strain gauge transducer, providing a 5 mV/V nominal DC output over an excitation range of 5 to 12 Vdc.
